[asterisk-users] Outbound video Calls

Thu Jun 26 04:56:52 CDT 2008

Hi all,

I am trying to make an outbound video call to a mobile from asterisk.
however it keeps failing.

I can make inbound calls from a mobile and view video.
I am using x-lite to initiate the outbound call, however I have tried using
the management interface as well (action: etc...) and result is the same.

normal voice outbound calls work fine.

Circuit is a q931 30 channel from telewest (virgin media).

Any pointers would be appreciated.

below is pri debug output and relevant conf entries.
